Definitions

  • the present invention relates to closure caps for sealing glass or plastic containers and more particularly to an improved composite closure cap having a metal cover and molded plastic container engaging ring.
  • Composite closure caps are well known and are widely used which include a disc-like cover portion inserted into circular molded plastic ring with the ring providing threaded or other means for attaching the composite cap to the container.
  • a sealing gasket is provided on the metal cover and tamper indicating means are provided sometimes in the form of a vacuum indicator button on the cover with or without an additional tamper indicating band provided as a portion of the molded plastic ring.
  • an object of the present invention is to provide an improved composite closure cap.
  • Another object of the present invention is to provide a composite closure capable of maintaining its seal through retorting or other heating operations.
  • Another object of the present invention is to provide an improved composite closure with more effective tamper in­dicating means including a positive tamper indication before loss of the seal or the package vacuum.
  • the closure 1 is applied to and seals a glass or plastic container 2 with the integrity of the seal being indicated by a tamper indicating band 3 forming the lower portion of the plastic ring 4.
  • the molded plastic ring 4 is formed with a skirt portion 5 including inwardly directed threads 6 for engaging cooperating threads 7 at the container mouth.
  • a radially inwardly directed flange or partial cover 8 is formed at the top of the plastic ring 4. Together with the skirt portion 5 it forms a cover engaging corner with the inner cover edge 9 engaging and forcing the cover 10 into sealing engagement with the container rim 11.
  • the tamper indicating band 3 forms the lower portion of the plastic ring 4 and it is attached to the skirt portion 5 of the plastic ring 4 at a line of weakness comprising an interrupted cut 12.
  • the cut 12 extends completely around the plastic ring 4 and is interrupted periodically by break-away ridges 13. Other lines of weakness such as grooves or others may be used.
  • the tamper indicating band 3 has an inwardly directed bead 14 for engaging a cooperating outwardly directed bead 15 on the container 2.
  • the bead 14 has a sharply tapered lowered surface 16 to facilitate its passage over the container threads 7 and the container bead 15 during the container sealing operation.
  • the upper surface 17 of the bead 14 is relatively horizontal to insure its engagement with the container bead 15 and to insure an adequate breaking force to tear the band 3 free when the closure 1 is removed in the manner illustrated in FIGS. 5 and 6.
  • the lower edge of the tamper indicating band 3 has a downwardly projecting thin skirt portion 18 which acts as a barrier for glass particles or dirt or other contam­inants during package shipment and storage to keep the contam­inants out of any space behind the plastic ring 4 such as the circular space illustrated at 19 (FIG. 4).
  • FIG. 3 illustrates the preferred cover 10 and sealing gasket 20 positioned at the outer portion of the cover 10.
  • the preferred material for the cover is tin plate although various rigid plastics including composites may be used to form the cover.
  • the preferred cover 10 has a downwardly and inwardly tapered outer edge portion 21 and terminates at the outer edge of the cover 10 in a depending cover skirt 22.
  • the plastisol or other flowed-in sealing gasket 20 is positioned in the corner between the skirt 22 and the tapered portion 21. It has a substantially vertical and relatively thick side sealing portion 23 covering the skirt 22 from its lower edge and has a radially inwardly directed top sealing portion of decreasing thickness towards its radial inner edge 24.
  • FIG. 4 illustrates the closure 1 in its sealed position with the cover 10 held tightly against the container rim 11 by the flange 8 of the band 4 with the top sealing portion of the gasket 20 pressed into sealing engagement with the container rim 11 and with the side sealing portion pressed into sealing engagement with a generally cylindrical and smooth side sealing surface 25 at the container rim.
  • cover 10 and seal has a number of advantages.
  • One advantage is the resistance of the closure 1 to vacuum loss or other loss of seal due to minor dimensional changes in the closure ring 4 or cover 10 during handling and partic­ularly during retorting where the package is subjected to a raised temperature. Even though the plastic ring 4 may move outwardly and/or upwardly with a corresponding upward or radial movement of the cover 10, either the top sealing portion or the side sealing portion of the gasket 20 will remain in sealing contact with the container 2. If the cover 10 is formed with a raw edge at the lower edge of its skirt 22, the edge is preferably coated with a rust preventing coating.
  • FIG. 4 illus­trates the tamper indicating band 3 having its bead 14 engaged with a cooperating bead 15 on the container.
  • FIG. 4 also illustrates the preferred plastic ring 4 threads 6 being in firm engagement with the container threads 7 and having sub­stantial cross-sections for providing an effective and stable threaded connection between container 2 and closure 1.
  • the lower surface of the bead 14, as well as the lower surfaces of the threads 6 on the plastic ring 4 have a sharp taper or acute angle with the verical facilitating the application of the closure 1 and in particular permitting the tamper indic­ating band 3 to move readily downwardly into its engaged pos­ition without fracturing during closure 1 application.
  • the generally horizontal upper surface of the bead 14 as well as the upper surfaces of the plastic ring threads 6 assist in providing a firm sealing action.
  • FIG. 4 also illustrates the downwardly depending skirt 18 provided on the tamper indicating band 3 which acts as a barrier preventing the entry of glass particles or other contaminants behind the tamper indicating band 3 or other portions of the plastic ring 4.
  • the preferred shape of the container 1 neck adjacent the tamper indicating band 3 has a steeply inclined upper portion 26 as well as a steeply in­clined connecting portion 27 between the portion 26 and the remainder of the container 1 whereby the upper portion permits the tamper indicating band skirt 18 to be positioned immediately adjacent to the container 1 surface as a barrier and to prevent any accumulation of particles on the container 1 at 27.
  • FIG. 5 illustrates an initial opening of the package as the closure 1 is turned only slightly upwardly to the position illustrated where the plastic ring 4 is clear of the cover 1 and the tamper indicating band 3 has been broken free.
  • the tamper indicating band 3 drops to the position illustrated giving a clear indication that the closure 1 has been tampered with or lifted itself from the package.
  • An abutment ring 28 in the ring 4 is still positioned slightly below the lower edge of the cover skirt 22 so that it is ineffective in lifting the cover 10 to break the package vacuum.
  • the upper portion of the plastic ring 4 therefore has a "floating action" per­mitting a short vertical movement before the cover 10 is lifted clear of the container 1 to break the vacuum thereby assuring a clear indication by the downward movement of the tamper indicating band 3.
  • FIG. 5 illustrates the package after the closure has been further removed and as the abutment ring 28 on the plastic ring 4 has lifted the cover 10 clear of the container rim 11 to break the seal and release the package vacuum.
  • FIGS. 3 thru 6 illustrate a cover with a vacuum indicating button 29 providing a secondary tamper indication and FIG. 6 shows the button 29 in its raised or vacuum released position.
  • FIG. 7 illustrates another embodiment of a composite closure cap 30 in which the plastic ring 31 has a modified upper portion which permits the cover to be inserted in the plastic 31 ring from the top.
  • the cover 32 is pressed downwardly permitting its flexible outer hooked edge 33 to snap under the top bead 34 on the plastic ring 31.
  • the cover 32 includes the above described top and side seal gasket shape, as well as the cover spacing which permits the floating action described above and the positive tamper indicator band action for indicating tampering before the package vacuum has been destroyed.
  • an improved composite closure which gives protection against loss of seal or vacuum during package handling and/or retorting and additionally provides a package which gives a positive tamper indicating ring action in advance of package vacuum loss.
  • the improved closure also provides a package with increased resistance to the entry of glass particles or other contaminants which may lodge behind closure cap skirts and thus enter the package during package opening.
